CHAPTER 4 PROPERTIES OF MATERIALS Fly Ash Fly ash, the fine particulate waste material produced by pulverized coalbased thermal power station, is an environmental pollutant, it has a potential to be a resource material. It is nowadays used in cement, concrete and …

ASME Coal Fineness Sampling Test Procedure Rev. 3/2010 Page 3 • Traverse points will need to be marked on the sampling probe based on an equal area test grid. Traverse points for a circular duct or pipe are calculated by first selecting the diagram below that

Coal Particulate Size and Fineness Figure 7 shows the coal fineness from the sampled particulates of the four PC pipes for the two elevations from mills 20 and 40 respectively. According to plant requirements, more than 70% (by weight) of the pulverized coal should be smaller than 75 μm.

The adverse effects are compounded because burners having more coal will likely be of lower fineness making it even more difficult to achieve complete combustion in the burner belt zone. Importance of Fineness. Poor Coal Fineness often yields poor distribution as large coal particles air mix to form a (2) phase mixture which will not homogenize.

Collecting coal samples using an isokinetic probe provides the best data describing actual operating conditions inside the coal pipe. Source: Storm Technologies Inc. The isokinetic coal sampling method, although more difficult, is the best option for determining the true mill coal fineness produced and to calculate pulverizer performance.
